ROOF FLASHING Filed May 5. 1928 2 Sheets-Shae! 2 Patented May 5, 1931STATES PATENT OFFICE WALTER- P. BUDD, OF DURHAM, NORTH CAROLINA ROOFFLASHING This invention relates to improvements in roof flashingconstructions.

The primary object of this invention is the provision of a practical andeconomical flashing construction, which embodies a flashing holder whichmay be built into a brick or concrete parapet wall above the roof as thebuilding is constructed, having an improved flashing apron adapted fordetachable assoio ciation with the wall and roofing.

A further object of this invention is the provision of an improvedflashing construction particularly well adapted for anchorage inconcrete parapet walls and the like,

by means of which flashing may be eiflciently attached in place in aneconomical man ner, to provide a positive water-seal at the juncture ofthe roof deck and wall.

Other objects and advantages of this in- '21) vention will be apparentduring the course of the following detailed description.

In the accompanying drawings, wherein for the purpose of illustration isshown a preferred form of this invention.

Figure 1 is a perspective view of a metal strip or member which isadapted to be embedded in a concrete parapet or other wall above theroof deck, during the formation thereof, and which has associatedtherewith means to hold the apron and other roofing flashing.

Figure 2 is a view showing the member of Figure 1 held by the form forthe concrete wall, and showing the relation which the same bear-s to theform and wall, prior to the removal of the form.

Figure 3 shows the flashing holder of Figures l and 2 in its relationafter the form work for the wall has been removed, and

49 showing the attachment of the apron flashing thereto at anintermediate step.

Figure 4 shows the improved roof flashing in place at the juncture of aconcrete wall and roof deck.

Figure 5 is a fragmentary perspective view, partly in section, takenthrough a part of the flashing holder of Figure 1, showing theconstruction thereof by means of which the same may be attached to formwork, and permit the latter to tear loose therefrom.

Figure 6 is an enlarged sectional view showing the relation in which theflashing holder of Figure l is attached to the form work, so as toenable the latter to tear loose from the flashing holder.

Figure 7 is an inside elevation of the apron attaching flange of theholder of Figure 6, showing more particularly the opening adapted toreceive the attaching nail by means of which the holder is secured inplace to form work during the construction of the wall.

The improved flashing construction is adapted to be used moreparticularly at the juncture of parapet walls with roof decks.

To this end, the roof deck F adjacent the wall B, is provided with roofcovering material 15, which extends over the deck F and upwardly alongthe outer face of the wall B, as is shown at 16 in the drawings, to

cover the juncture at the connection of the base of the wall with theroof deck. Ordinary flashing 17 which may be of composition, sheetmetal, or other material, is bent in an L-shaped relation at thejuncture of the roof deck with the wall, to overlie the roofing material15 and 16; said ordinary l.shapcd flashing 17 including a portion 18overlying the roofing 15 on the roof deck, and the upstanding portion 19along the outer face of the wall overlying the portion 16 of theroofing, as shown in both forms of the invention.

Referring to the sheet metal flashing holder A,adapted to be used inconcrete walls; the same comprises a body portion 20 adapted to beembedded in the concrete wall in a hori zontal position. The body 20 iscorrugated, preferably longitudinally as shown at 21 in the drawings, inorder to strengthen the same. The corrugations extend longitudinally,and in cross section the body 20 of the strip of course has a wavy orgrooved appearance. Along the rear margin the body 20 is provided withan upstanding vertical protecting flange 23, which in heightapproximates an inch, although this may vary. The purpose is to preventseepage of water along the body and into the wall, and keep moistureabove the body. The flange 23, of course, has another function, and thatis of providing brace arms for supporting the strip A on the form workduring the construction of the wall. To this end, arms 2i are struckfrom the ma terial ot' the flange 23, the arms 24 being strucklongitudinally from the flange 23, along a division line which extendsparallol with the upper and lower edges of the flange 23, and the arm 2ais severed at 26, at one end, from the flange, but at the other end itis integrally connected with the flange, and on which end the bracearm24 is twisted, as shown at 27 in Figure 2 of the drawings, to positionthe brace arm 24: transverse to the flange 23, and in an upward diagonaland divergent relation with respect to the horizontal body 20.

Along the opposite marginal longitudinal portion of the body 20, anupstanding attaching flange 30 is provided, which is of approximatelythe same height the flange 23, and at the upoer edge thereof the flange30 has a depending flange 32 connected therewith, and depending alongthe outer side of the flange 30, in spaced relation therewith to providea socket The flange 32 in width about one-half the width oi" the flange30, and as above mentioned is normally bent transverse in upstandingvertical relation with respect to the body 20. At spaced intervals alongthe flanges 30 and 32, the same are provided with pairs of aligningopenings. These aligning openings consist of a large opening 35 punchedor otherwi e termed in the flange 30, and a concentric aligning smalleropening 36 in the flange 32. The flange 32 "from the tree edge 37thereof, in right angled relation therewith to each oi the openings 36,is split, as shown at 38 in Varions views of the drawings, for a purposeto be subsequently described.

Referring to the manner of. attachment of the holder A in the wall ii.the term work tor receivin the poured con rote is suitably placed. andit includes a board or member ll} placed upon the root to torni andshape the inside surface ot the wall ll. ()n the inside "face ll of thismember 40, the flanges E30 and 32 are attached by na s 42, or otherappropriate securing elemen t c said nails being driven through theopenings 35 and 36, and into the board or member s0, with the head i8lying against the inside surface of the flan 30. The nails 42 are ofsuch size that the heads L3 are approximately the same diameter, butjust slightly more than the diameter of the larger opening 35 in theflange 30. The flanges 30 and are thus secured tightly against theinside surface of the board or member to, in order to position the body20 of the sheet n etal attaching strip A in a horizontal plane. Thebrace arm 24 is bent at 27 in the manner above described and positionedin an upwardly sloping relation towards the form 40, above the body 20,and at its free end it is flanged or bent at 46. This end 46 is providedwith openings l7 therethrough, "for receiving nails 48, by means ofwhich to attach the arm 2-l at its free end against the form member ll),as illustrated in Figure 2 of the drawings.

he flange 30 is secured at spaced intervals along the length thereof tothe form member 40, and the arms 21 are provided at spaced intervalsalong the strip A and secured as above described in a bracing relationto support the body 20 in a horizontal position on the form L0. Theconcrete is then poured ito the form, and the entire body 20 and bracearms 24- are covered, and the poured concrete is allowed to harden.

WVhen the wall B is sufliciently hard, the form member 40 is removed,and since the opening 35 is about the same as the head of the nails 42,the heads of the nails may be torn through said openings 'ithoutdestroying the flange 30, and due to the split 38 running thru theopening 36, the nails may be readily removed from the openings 35,without materially injuring the flange 32. Inasmuch as the flanges 46 ofthe brace arms 2 perform no function in connection with flashing theroot, it does not matter if the renu *al of the form 4.0 tears theflanges 4G. Ordinarily, however, the nails 48 will tear out the flanges46 without materially injuring the same, and. the flanges 46 may then bebent downwardly over the outer surface of the wall B as shown in Figures3 and 4c of the drawings. lVhen the form ll) is removed. it will tearthe flanges 30 and 32 loose from the face 60 ot' the wall B, into anoutstanding relation theretrom, and the flanges 30 and 32 are thentransverse in a right angled relation with respect to the wall (30, asillustrated in Figure 3 of the drawings.

After this. however. the apron may be assembled in the space 33 betweenthe flanges 530 and 32.

Referring to the construction of the apron flashing E. the samepreferably comprises an elongated body strip 70, which is relativelywide, and the upper edge thereof is provided with a preferably rightangled flange 71, which is adapted to lit in the inwardly facing socket38 between the flanges 80 and 32 ot the holding strip A above described,with the body depending along the wall face 60 and overlapping theordinary flashing 19 at its lower skirt edge. The body 70 at the loweredge thereof is flanged at 73 in an angled re lation with respect to theplane of the body 70, and after the apron flashing has been assembled inthis manner in the socks 33 of the flanges 30 and 32, the said flanges30 and 32 are bent downwardly in a doubled relation over the body'FO, asshown in Figure 4 of the drawings, to draw the upper end of the apronhing flush against the inside surface of the wall 13, and this holds theapron flashing in a secured relation against the wall and against theupper portion of the ordinary flashing 17, in a positive leak-proofconnection at the juncture of the roof with the Wall B.
